[Tutor] extract a submatrix

[Bala subramanian]

Friends,
Excuse me if this question is not appropriate for this forum. I have a
matrix of size 550,550. I want to extract only part of this matrix say first
330 elements, i dnt need the last 220 elements in the matrix. is there any
function in numpy that can do this kind of extraction. I am quite new to
numpy. How can do the same ?

Thank you,
Bala
